Broken Link Checker

Broken Link Checker. Find 404s and dead links on the current page. Scan the page and detect redirects.

🎯 WHY BROKEN LINK CHECKER EXISTS Every website accumulates broken links over time. Pages get deleted, partners change their URLs, blog posts rot, and suddenly your visitors are hitting 404 walls instead of the content they came for. Each dead link quietly erodes trust, increases bounce rate, and tells search engines your site is poorly maintained. Broken link checker tools usually mean pasting URLs into a slow web crawler, waiting in a queue, and hitting a paywall after ten links. This extension puts the whole check one click away, right in your browser, on the exact page you are looking at. No account, no waiting, no data sent anywhere. 🚀 HOW IT WORKS ▸ Open any page you want to audit ▸ Click the Broken Link Checker icon and hit Scan Page ▸ Every link on the page is checked live: working, broken, redirect, or timeout ▸ Review the results, sort by status, and export the full report as CSV The scan runs entirely in your browser. Your pages, your links, your data: nothing touches our servers. 👥 PERFECT FOR 🧑‍💻 **SEO freelancers**: audit client sites on the spot and hand over a CSV report in minutes ✍️ **Bloggers and content teams**: keep years of old posts free of dead outbound links 🛒 **Store owners**: catch broken product and category links before customers do 🏢 **Agencies**: run a quick link health pass as part of every site review 🎓 **Researchers and students**: verify that cited sources still resolve ✨ KEY FEATURES ✅ **One-click page scan**: checks every link on the current page in seconds ✅ **Real HTTP status codes**: see the actual 404, 500, or 301 behind every link ✅ **Redirect detection**: spot chains and moved pages, not just hard errors ✅ **Timeout detection**: find links that hang forever, the worst user experience of all ✅ **CSV export**: one click to a spreadsheet-ready report for clients or teammates ✅ **Scan history**: recent scans stored locally so you can compare over time ✅ **Privacy first**: all checks run in your browser, nothing is uploaded 📖 HOW TO USE → Install and pin the extension to your toolbar → Navigate to the page you want to check → Click the icon, then Scan Page → Grant the one-time permission that lets the extension check link status → Sort, filter, and export your results 💡 PRO TIPS 💡 Scan your most-visited pages first: that is where broken links cost you the most 💡 Sort by status code to fix hard 404s before chasing redirects 💡 Export before and after a cleanup to document the improvement for clients 💡 Rescan monthly: link rot never stops ❓ FREQUENTLY ASKED QUESTIONS Q: Does it scan my whole website? A: It scans the page you are on, every link on it. For a full-site audit, scan your key pages one by one: home, category pages, top posts. Q: Why does it ask for permission to access websites? A: Checking whether a link is dead requires requesting that link. The permission is optional and only requested when you start your first scan. Q: Is my browsing data collected? A: No. Scans run locally, results are stored locally, and nothing is transmitted to any server. Q: What counts as a broken link? A: Any link returning a 4xx or 5xx status, plus links that fail to respond before the timeout. Q: Does it work behind logins? A: Yes. Because the scan runs in your browser session, pages that require login are checked with your own access. ⚡ TECHNICAL NOTES • Manifest V3, minimal permissions: storage, activeTab, scripting • No background crawling, no persistent content scripts • Checks run with your browser's own network stack, including cookies for authenticated pages • Lightweight: no external libraries, no tracking SDKs 💎 FREE VS PRO The free version covers everyday page checks.
